[U-Boot] [PATCH v2 4/4] lin_gadget: use common linux/compat.h

[Anatolij Gustschin]

From: Mike Frysinger <vapier at gentoo.org>

Merge our duplicate definitions with the common header.
Also fix drivers/usb/gadget/s3c_udc_otg_xfer_dma.c to
use min() instead of min_t() since we remove the latter
from compat.h.
